Atlantic Tarpon - Geographical Distribution and Migration

Geographical Distribution and Migration

Since tarpons are not commercially valuable as a food fish, very little has been documented concerning their geographical distribution and migrations. They inhabit both sides of the Atlantic Ocean. Their range in the eastern Atlantic has been reliably established from Senegal to the Congo. Tarpons inhabiting the western Atlantic are principally found to populate warmer coastal waters primarily in the Gulf of Mexico, Florida, and the West Indies. Nonetheless, tarpon are regularly caught by anglers at Cape Hatteras and as far as Nova Scotia, Bermuda, and south to Argentina. Scientific studies indicate schools have routinely migrated through the Panama Canal from the Atlantic to the Pacific and back for over 70 years.They have not been shown to breed in the Pacific Ocean, but anecdotal evidence by tarpon fishing guides and anglers indicates it is possible, as over the last 60 years, many small juveniles and some mature giants have been caught and documented, principally on the Pacific side of Panama at the Bayano River, in the Gulf of San Miguel and its tributaries, Coiba Island in the Gulf of Chiriquí, and at Piñas Bay in the Gulf of Panama. Since Tarpons tolerate wide ranges in salinity throughout their lives and will eat almost anything dead or alive, their migrations seemingly are only limited by water temperatures. Tarpons prefer water temperatures of 72 to 82°F, below 60°F they become inactive, and temperatures under 40°F can be lethal.
